A three week industrial dispute has ended at one of Tasmania's two major meat works.

Workers picketed Greenham's meat processors almost a month ago to protest the terms of an enterprise bargaining agreement that would see new employees start at a lower wage.

The company re-negotiated it's offer, raising the pay increase, but did not waver on the wage structure changes.

Head of the Tasmanian Meat Workers Union Troy Baker says the company showed him figures that suggested the business would not be viable in the long term unless new employees are paid less.

"The people just didn't want to see the industry wages go backwards - they couldn't see the sense in going backwards," he said.

"But when they sat back and looked at it with a percentage rises on top, over time it would have made the company hard to be viable in another four years' time."

With an original offer of 2.5 per cent wage increase across the board, workers have accepted a 2.5 per cent increase in pay with a $750 sign-on bonus for the first two years, which will increase to a 3 per cent increase in pay for the last two years of the agreement.
